How is this meter powered? Does it require an AC power adapter?

When the meter is connected to AC voltage, that powers the meter. Be careful to get the current transformer connected to the terminal. In my meter it was the green terminal, but follow the diagram that is on the box or with the meter.

The wiring diagram is somewhat confusing, but it draws power from the same source that it is measuring.
6297
The meter is powered by the voltage its monitoring. No external source required.

This model is straight wired. It has an internal adapter. Wire a hot and a neutral to it if it's a 110v circuit. Wire both hot poles to it if it's a 240v with A and B Hot feeds.

No, the unit powers from the AC voltage being metered (and the current measurement needed for the power calculation comes from a small toroid which is included). Thus four terminals: two for the voltage measurement and two for the toroid leads.

This meter can be powered from one 120 volt source, or two 120 volt sources if you want the LCD screen to read 240 volts. It does not require an AC power adapter, you can just rob power from your breaker panel. Run a wire from a 120 volt line into the meter and the screen will light up.

There is an AC adapter with the unit. That is the only way I can see to power it.

It is 12V DC and comes with an AC adapter. I used one of the adapters that came with my Q-See Security system which seem pretty standard and it works fine.

Yes, the USB charging circuit in this outlet does use power even when nothing is plugged in. I tested by wiring a Mastech MS8264 digital multimeter in series with the hot lead that powers the outlet. With nothing plugged into the outlet, the multimeter read 0.42-0.44 milliamps at 120VAC. Note that this is not a true-RMS multimeter; the actual power draw was probably more like 0.66 milliamps. That's less than 1/10th of a watt, which might be so little that it doesn't matter to you, but it is definitely nonzero and does add up over time. For comparison, I also measured a FastMac U-Socket, a competitor to this device. The U-Socket reading showed about 2/3 of the current that this one drew (with nothing connected to either device). I chose to keep this one because it is easier to fit into a gang box and seems to have a sturdier USB port design.

Yes it does require a totally separate power supply for the volt amp meter then the battery you are measuring.

The meter must have its own, separate power supply. I use a 12vdc transformer plugged into my inverter and it works great. I am able to monitor amps used by the inverter and other DC loads connected to my batteries as well as switch to see battery voltage. If you already have a separate power supply, you may have a bad meter.

I believe mine came with an AC Adaptor. I don't USB would be enough even if it was an option.

I don't use this meter for ac work. I checked the meter and the info I got with the meter ( which is not much). But it will not do what you want . sorry not much help. Bill

I don't own the unit yet however yes this does require an AC adapter. It looks to be on the front of the unit in the bottom left corner (look at the 3rd picture you can see it).

No, it needs to be plugged in as it comes standard. I have no idea if you can buy some kind of adapter.

Sorry for the late reply:I think the wattage is calculated using an algorithm (speed, incline, etc.). I have never used a power meter before so I am afraid I cannot comment on how accurate it is.

It's battery operated, however, you can also use an AC adapter, but that's not included.

The adapter I have is AC powered and not battery operated. I don't understand the question: "without AC adapter..." and "rather than battery operated." If it is not powered by AC or a battery, how is it supposed to be powered. This unit plugs into an earphone receptacle on the computer. These ports don't supply power like a USB port does. I don't think my answer helps much.

It is a three prong unit. It plugs into a standard outlet. Keep the ground and don't use an adapter in my opinion.

The unit I'm using gets it's power from the devices it is attached to. Thus, I am not using a power adaptor with it. However, if you need one they are available in many stores that sell electrical devices.

It is powered from the laptop itself. I plug my (Dell) laptop in (by way of 110vt. adapter) and use it, otherwise you will be draining your laptop battery pretty fast.

Just received mine and it came with a AC adapter that fits my outlet into the converter. I thought that it was non standard battery powered so this should be a plus. Now to find out if it actually works.
